The instructions in the phone show that you have to go through all these menus and press a bunch of buttons to finally be able to voice activate. I don't want to bother pressing a bunch of buttons while driving.
Do you know how to set up the Samsung phone so that I can press ONE button, say the name, and that's it?
thanks
